TE Connectivity AMP Connectors 103638-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 103638-8 is a rectangular connector header designed for through-hole mounting applications. This 9-position, single-row connector operates at a 0.100" (2.54mm) pitch and features shrouded 4-wall construction with male pin contacts. The connector is terminated through solder and incorporates a latch holder fastening mechanism.

The 103638-8 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement. Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance requirements.

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Latch Holder)
• Insulation material (Thermoplastic)
• Contact shape (Square)

Physical Dimensions:

• Contact length - mating (0.230" / 5.84mm)
• Contact length - post (0.130" / 3.30mm)
• Insulation height (0.535" / 13.60mm)

The substitute part 5-104363-8 maintains full equivalence across all critical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-104363-8 is the direct substitute for the discontinued 103638-8. Both connectors are manufactured by TE Connectivity within the AMPMODU MTE series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Advantage: The 5-104363-8 is currently active in production, ensuring long-term availability and supply chain continuity. The 103638-8 is discontinued at DiGi Electronics, making the 5-104363-8 the appropriate selection for new designs and ongoing component procurement.

Compliance and Certification: The 5-104363-8 provides enhanced compliance status:

• RoHS Compliant (versus RoHS non-compliant for 103638-8)
• UL94 V-0 material flammability rating (not specified for 103638-8)
• Operating temperature range specified at -65°C ~ 105°C
• Current rating specified at 3A

These certifications and specifications are provided for the 5-104363-8 and represent additional documentation available for this active product variant.

Functional Equivalence: All core connector parameters remain identical between the two parts, including contact configuration, pitch, shrouding, termination method, and physical dimensions. The 5-104363-8 is a direct functional replacement suitable for all applications previously served by the 103638-8.

Frequently Asked Questions (FAQ)

Q: Can the 5-104363-8 be used as a direct replacement for the 103638-8 in existing designs?

A: Yes. The 5-104363-8 maintains identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, mounting method, shrouding, and physical dimensions. No design modifications are required.

Q: What are the key differences between these two parts?

A: The primary differences are product status and compliance documentation. The 5-104363-8 is currently active in production, while the 103638-8 is discontinued. The 5-104363-8 includes RoHS compliance certification, UL94 V-0 flammability rating, specified operating temperature range (-65°C ~ 105°C), and specified current rating (3A). The 103638-8 does not provide these specifications.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both connectors share identical contact lengths (mating: 0.230" / 5.84mm; post: 0.130" / 3.30mm) and insulation height (0.535" / 13.60mm). The 5-104363-8 specifies an overall contact length of 0.550" (13.97mm), which is not provided for the 103638-8.

Q: What is the pitch specification for these connectors?

A: Both connectors operate at a 0.100" (2.54mm) mating pitch, which is the standard spacing for AMPMODU MTE series headers.

Q: Are there packaging differences between these parts?

A: The 5-104363-8 is supplied in Tube packaging. Packaging information is not specified for the 103638-8.

Q: Do these connectors support the same applications?

A: Yes. Both parts are rated for identical applications: Automotive, General Purpose, Medical, and Telecommunications.

Q: What is the contact finish specification?

A: Both connectors feature gold-plated mating contacts (15.0µin / 0.38µm thickness) with tin-lead or tin post finish (100.0µin / 2.54µm thickness). The 5-104363-8 specifies tin post finish, while the 103638-8 specifies tin-lead.

Q: Are these connectors RoHS compliant?

A: The 5-104363-8 is RoHS Compliant. The 103638-8 is RoHS non-compliant. For applications requiring RoHS compliance, the 5-104363-8 is the appropriate selection.
